Distinguishing between spot and torus models of high-frequency quasiperiodic oscillations
V. Karas, P. Bakala, G. Torok +8
In the context of high-frequency quasi-periodic oscillation (HF QPOs) we further explore the appearance of an observable signal generated by hot spots moving along quasi-elliptic t…

Spectral signature of oscillating slender tori surrounding Kerr black holes
F. H. Vincent, G. P. Mazur, O. Straub +4
Context. Some microquasars exhibit millisecond quasi-periodic oscillations (QPO) that are likely related to phenomena occuring in the immediate vicinity of the central black hole.…

Power density spectra of modes of orbital motion in strongly curved spacetime: obtaining the observable signal
P. Bakala, G. Torok, V. Karas +8
High frequency quasi-periodic oscillations (HF QPOs) appear in the X-ray variability of several accreting low-mass binaries. In a series of works it was suggested that these QPOs m…
